01B TANK.

,Oil tield tanks are usuallyemployed with an opening normally elosed'byV a pivoted cover, and 'which opening is provided forthe purpose of nspectine' and ,measuring .the contents Vof the tank from time to time, use beingmadeof a suitable measuring instru ment which is inserted linto `the tank subsequent to the opening of said cover. l

t is the purpose `of the present invention toy provide an improved cover for said opening, and to associate therewith means for supporting the cover horizontally in an open position, in which position the cover caribe employed as a support :tor the measuring instrument, to allow the oil to drain from "he measuring instrument onto the cover,`

which is designed to collect the oil and return it to the tank as the cover is closed.

The nature and advantages of the invention will be better understood when the following` detail description is 'read in connecf tion with the accompanyingdrawing, the invention residing in the construction, combination and arrangement of parts as claimed. i

In the'dratvinp,` forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a fragmentary showing the cover supported,horizontally in opened position, and the. measuring instrument arranged thereon. Y D

Figure 2 is a fragmentary sectional view 'showing the cover closed.

Figure 3 is a fragmentary sectional view of the neck of the tank. v

.Figure 4 is a sectional view through the cover.

Referring to the drawing` in detail 10 represents a portion of an oil ield tank which has bolted or otherwise suitably secured there-to `a neck portion 11` which eommunicates with the tank, and through which neck portion the tank is inspected from time to time and the contents measured by what is commonly knoivnas a thief, which is adapted to be inserted Within the tank through the neck portion, subsequent to the opening of the cover 13 therefor'. This cover is provided with a bracket arm 14 which isv pivoted to a similar arm 14. in a manner to permit the co-ver to be swung to an open position Wholly to one sideof the neck portion, when it is desired to inspect or measure the contents of the tank 10. VA `gasket 16 is seview of a tank cured to thetlanee 15formed on the neck, to `provide a fluid-tight connection between the Atank and cover When the latter is closed.

The cover is ,effectivelyheld in its closed position by means of 'a pivotally mounted" `holt 17 adapted to be received between spaced lugs 1S projecting from the cover,v and,` to be subsequently engaged by a Wing nut 19 threaded on the bolt.

In accordance with the present invention the cover 13 is provided with an annular rim or tiangeQO to prevent. `the drippings from the thief from running off of the cover, When the latter is employed as a support for the thief in the manner illustrated in Figure 1. Vhile any suitablemeans may be employed for the purpose of supporting the cover horizontally in an opened position, so that it may be used as a support for the thief, I preferably provide the cover with a substantially U-sliaped member 21 which constitutes a. handle to facilitate opening or closing of the cover, and Vis also `used in' the .capacity of a support for the cover when the latter is opened. swung to an opened position, the U-shaped member reposes upon the top of the tank, thereby supporting the cover horizontally for use as a support for the thief. The latter when arranged on the cover is therefore alloWed to drain, and the oil falling upon the cover is subsequently emptied into the tank when the cover is closed. For this purpose the cover is provided With a metallic plate 22 supported bythe rim or flange 20, the

plate 22 being' spaced from the adjacent side tank 10, for Which `purpose the plate is slightly trough-shaped as clearly illust-rated in Figure 4. i

While it is believed that from the foregoing description,the nature and advantages of the invention Will be readily apparent, I desire to have it understood, that I do not liinit myself to what is herein shown and described and that such changes may be reln other Words when the cover is l lou sorted to When desired as fall Within the scope of what is claimed.

`What is claimed is:

l. In combination, a tank having a neck portion, a pivoted cover therefor adapted to be swung Wholly to one side of the neck to an opened position, an annular rim projecting from the underside of the cover, and a plate secured to said annular rim in spaced relation to the cover to forni a pocket to receive a liquid when the cover is swung to its closed position, said plate being curved transversely to guide and return the liquid into the tank as the cover is closed.

2. In combination, a tank having a neck portion, a pivoted cover therefor adapted to be swung Wholly to one side of the neck to an opened position, means carried by the cover and adapted to repose upon the tank to support the cover horizontally in its opened position, an annular riin projecting from the underside of the cover, a segmental plate secured to said riin and spaced from the underside of the cover to form a pocket by the intervening space adapted to receive a liquid as the cover is swung to a closed position, and said plate being curved to form a trough to guide the liquid into the tank as the cover is closed.

In testimony whereof I aix my signature.
